In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: do not allow SET_ID to refer to another table When doing lookups for sets on the same batch by using its ID, a set from a different table can be used. Then, when the table is removed, a reference to the set may be kept after the set is freed, leading to a potential use-after-free. When looking for sets by ID, use the table that was used for the lookup by name, and only return sets belonging to that same table. This fixes CVE-2022-2586, also reported as ZDI-CAN-17470.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 4.14.318-240.529. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2100 advisory.

    It was discovered that a nft object or expression could reference a nft set on a different nft table,     leading to a use-after-free once that table was deleted. (CVE-2022-2586)

    A heap buffer overflow flaw was found in the Linux kernel's Netfilter subsystem in the way a user provides     incorrect input of the NFT_DATA_VERDICT type. This flaw allows a local user to crash or potentially     escalate their privileges on the system. (CVE-2022-34918)

    In the Linux kernel, the following vulnerability has been resolved:

    btrfs: unset reloc control if transaction commit fails in prepare_to_relocate() (CVE-2022-50067)

    In the Linux kernel, the following vulnerability has been resolved:

    netfilter: nf_tables: do not allow SET_ID to refer to another table (CVE-2022-50213)

    A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

    do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

    A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation.

    The out-of-bounds write is caused by missing skb->cb  initialization in the ipvlan network driver. The     vulnerability is reachable if CONFIG_IPVLAN is enabled.

    We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

    A use after free vulnerability was found in prepare_to_relocate in fs/btrfs/relocation.c in btrfs in the     Linux Kernel. This possible flaw can be triggered by calling btrfs_ioctl_balance() before calling     btrfs_ioctl_defrag(). (CVE-2023-3111)

    A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the     Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading     to a kernel information leak. (CVE-2023-3141)

    An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. (CVE-2023-34256)

    A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This     flaw allows a local user to cause an information leak problem while freeing the old quota file names     before a potential failure, leading to a use-after-free. (CVE-2024-0775)

    In the Linux kernel, the following vulnerability has been resolved:

    i2c: Fix a potential use after free

    Free the adap structure only after we are done using it.This patch just moves the put_device() down a bit     to avoid theuse after free.

    [wsa: added comment to the code, added Fixes tag] (CVE-2019-25162)

    In the Linux kernel, the following vulnerability has been resolved:

    tun: avoid double free in tun_free_netdev (CVE-2021-47082)

    A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user     forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local     user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)

    A flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it     possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This     flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel     oops condition that results in a denial of service. (CVE-2022-2153)

    A use-after-free flaw was found in the Linux kernel's POSIX CPU timers functionality in the way a user     creates and then deletes the timer in the non-leader thread of the program. This flaw allows a local user     to crash or potentially escalate their privileges on the system. (CVE-2022-2585)

    It was discovered that a nft object or expression could reference a nft set on a different nft table,     leading to a use-after-free once that table was deleted. (CVE-2022-2586)

    A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the     Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege     escalation problem. (CVE-2022-2588)

    An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

    An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the     bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to     gain unauthorized access to data. (CVE-2022-2905)

    A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

    A use-after-free flaw was found in io_uring in the Linux kernel. This flaw allows a local user to trigger     the issue if a signalfd or binder fd is polled with the io_uring poll due to a lack of io_uring POLLFREE     handling. (CVE-2022-3176)

    A vulnerability was found in Linux Kernel. It has been classified as critical. This affects the function     devlink_param_set/devlink_param_get of the file net/core/devlink.c of the component IPsec. The     manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier     VDB-211929 was assigned to this vulnerability. (CVE-2022-3625)

    An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

    An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of     service can occur upon binding to an already bound chain. (CVE-2022-39190)

    A race condition in the Linux kernel's EFI capsule loader driver was found in the way it handled write and     flush operations on the device node of the EFI capsule. A local user could potentially use this flaw to     crash the system. (CVE-2022-40307)

    mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale TLB because an rmap lock is     not held during a PUD move. (CVE-2022-41222)

    A double-free flaw was found in the Linux kernel's TUN/TAP device driver functionality in how a user     registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier).

    -- the list head is all zeroes, this results in a NULL pointer dereference. (CVE-2023-1095)

    The upstream advisory describes this issue as follows:

    This vulnerability allows local attackers to disclose sensitive information on affected installations of     the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target     system in order to exploit this vulnerability.

    The specific flaw exists within the processing of seg6 attributes. The issue results from the lack of     proper validation of user-supplied data, which can result in a read past the end of an allocated buffer.
    An attacker can leverage this in conjunction with other vulnerabilties to escalate privileges and execute     arbitrary code in the context of the kernel. (CVE-2023-2860)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 5.15.69-37.134. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2022-008 advisory.

    An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

    A flaw was found in the x86 KVM subsystem in kvm_steal_time_set_preempted in arch/x86/kvm/x86.c in the     Linux kernel. Unprivileged guest users can compromise the guest kernel because TLB flush operations are     mishandled in certain KVM_VCPU_PREEMPTED situations. (CVE-2022-39189)

    An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of     service can occur upon binding to an already bound chain. (CVE-2022-39190)

    In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the     transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list
    -- the list head is all zeroes, this results in a NULL pointer dereference. (CVE-2023-1095)

    A flaw was found in the Linux kernel's netdevsim device driver, within the scheduling of events. This     issue results from the improper management of a reference count. This may allow an attacker to create a     denial of service condition on the system. (CVE-2023-2019)

    A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors. (CVE-2023-2513)

    The upstream advisory describes this issue as follows:

    This vulnerability allows local attackers to disclose sensitive information on affected installations of     the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target     system in order to exploit this vulnerability.

    The specific flaw exists within the processing of seg6 attributes. The issue results from the lack of     proper validation of user-supplied data, which can result in a read past the end of an allocated buffer.
    An attacker can leverage this in conjunction with other vulnerabilties to escalate privileges and execute     arbitrary code in the context of the kernel. (CVE-2023-2860)

    A use after free vulnerability was found in prepare_to_relocate in fs/btrfs/relocation.c in btrfs in the     Linux Kernel. This possible flaw can be triggered by calling btrfs_ioctl_balance() before calling     btrfs_ioctl_defrag(). (CVE-2023-3111)

    A use-after-free flaw was found in btrfs_get_dev_args_from_path in fs/btrfs/volumes.c in btrfs file-system     in the Linux Kernel. This flaw allows a local attacker with special privileges to cause a system crash or     leak internal kernel information (CVE-2023-4394)

    A use-after-free flaw was found in the Linux Kernel. When a disk is removed, bdi_unregister is called to     stop further write-back and waits for associated delayed work to complete. However,     wb_inode_writeback_end() may schedule bandwidth estimation work after this has completed, which can result     in the timer attempting to access the recently freed bdi_writeback. (CVE-2024-0562)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 5.4.209-116.367. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-035 advisory.

    An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

    It was discovered that a nft object or expression could reference a nft set on a different nft table,     leading to a use-after-free once that table was deleted. (CVE-2022-2586)

    A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the     Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege     escalation problem. (CVE-2022-2588)

    In the Linux kernel, the following vulnerability has been resolved:

    netfilter: nf_tables: do not allow SET_ID to refer to another table (CVE-2022-50213)

Tenable has extracted the preceding description block directly from the tested product security advisory.
