In the Linux kernel, the following vulnerability has been resolved: ext4: allow ext4_get_group_info() to fail Previously, ext4_get_group_info() would treat an invalid group number as BUG(), since in theory it should never happen. However, if a malicious attaker (or fuzzer) modifies the superblock via the block device while it is the file system is mounted, it is possible for s_first_data_block to get set to a very large number. In that case, when calculating the block group of some block number (such as the starting block of a preallocation region), could result in an underflow and very large block group number. Then the BUG_ON check in ext4_get_group_info() would fire, resutling in a denial of service attack that can be triggered by root or someone with write access to the block device. For a quality of implementation perspective, it's best that even if the system administrator does something that they shouldn't, that it will not trigger a BUG. So instead of BUG'ing, ext4_get_group_info() will call ext4_error and return NULL. We also add fallback code in all of the callers of ext4_get_group_info() that it might NULL. Also, since ext4_get_group_info() was already borderline to be an inline function, un-inline it. The results in a next reduction of the compiled text size of ext4 by roughly 2k.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ext4: allow ext4_get_group_info() to fail Previously, ext4_get_group_info() would treat an invalid group     number as BUG(), since in theory it should never happen. However, if a malicious attaker (or fuzzer)     modifies the superblock via the block device while it is the file system is mounted, it is possible for     s_first_data_block to get set to a very large number. In that case, when calculating the block group of     some block number (such as the starting block of a preallocation region), could result in an underflow and     very large block group number. Then the BUG_ON check in ext4_get_group_info() would fire, resutling in a     denial of service attack that can be triggered by root or someone with write access to the block device.
    For a quality of implementation perspective, it's best that even if the system administrator does     something that they shouldn't, that it will not trigger a BUG. So instead of BUG'ing,     ext4_get_group_info() will call ext4_error and return NULL. We also add fallback code in all of the     callers of ext4_get_group_info() that it might NULL. Also, since ext4_get_group_info() was already     borderline to be an inline function, un-inline it. The results in a next reduction of the compiled text     size of ext4 by roughly 2k. (CVE-2023-53503)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of kernel installed on the remote host is prior to 5.15.117-72.142. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-021 advisory.

    In the Linux kernel through 6.2.7, fs/ntfs3/inode.c has an invalid kfree because it does not validate MFT     flags before replaying logs. (CVE-2022-48425)

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

    binder: fix UAF of alloc->vma in race with munmap() (CVE-2022-50240)

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

    binder: fix UAF of alloc->vma in race with munmap() (CVE-2022-50338)

    There is a potential deadlock in the eBPF subsystem in the Linux kernel.

    The default sysctl configuration kernel.unprivileged_bpf_disabled on Amazon Linux does not allow     unprivileged users to use eBPF. (CVE-2023-0160)

    A flaw was found in the Linux kernel's networking subsystem within the RPL protocol's handling. This issue     results from the improper handling of user-supplied data, which can lead to an assertion failure. This     flaw allows an unauthenticated, remote attacker to create a denial of service condition on the system.
    (CVE-2023-2156)

    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 flaw in the Linux Kernel found in the GFS2 file system. On corrupted gfs2 file systems the evict code     can try to reference the journal descriptor structure, jdesc, after it has been freed and set to NULL. It     can lead to null pointer dereference when gfs2_trans_begin being called and then fail     ingfs2_evict_inode(). (CVE-2023-3212)

    An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

    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 vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal     kernel information. (CVE-2023-3567)

    An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation. (CVE-2023-35788)
