In the Linux kernel, the following vulnerability has been resolved: Squashfs: fix handling and sanity checking of xattr_ids count A Sysbot [1] corrupted filesystem exposes two flaws in the handling and sanity checking of the xattr_ids count in the filesystem. Both of these flaws cause computation overflow due to incorrect typing. In the corrupted filesystem the xattr_ids value is 4294967071, which stored in a signed variable becomes the negative number -225. Flaw 1 (64-bit systems only): The signed integer xattr_ids variable causes sign extension. This causes variable overflow in the SQUASHFS_XATTR_*(A) macros. The variable is first multiplied by sizeof(struct squashfs_xattr_id) where the type of the sizeof operator is "unsigned long". On a 64-bit system this is 64-bits in size, and causes the negative number to be sign extended and widened to 64-bits and then become unsigned. This produces the very large number 18446744073709548016 or 2^64 - 3600. This number when rounded up by SQUASHFS_METADATA_SIZE - 1 (8191 bytes) and divided by SQUASHFS_METADATA_SIZE overflows and produces a length of 0 (stored in len). Flaw 2 (32-bit systems only): On a 32-bit system the integer variable is not widened by the unsigned long type of the sizeof operator (32-bits), and the signedness of the variable has no effect due it always being treated as unsigned. The above corrupted xattr_ids value of 4294967071, when multiplied overflows and produces the number 4294963696 or 2^32 - 3400. This number when rounded up by SQUASHFS_METADATA_SIZE - 1 (8191 bytes) and divided by SQUASHFS_METADATA_SIZE overflows again and produces a length of 0. The effect of the 0 length computation: In conjunction with the corrupted xattr_ids field, the filesystem also has a corrupted xattr_table_start value, where it matches the end of filesystem value of 850. This causes the following sanity check code to fail because the incorrectly computed len of 0 matches the incorrect size of the table reported by the superblock (0 bytes). len = SQUASHFS_XATTR_BLOCK_BYTES(*xattr_ids); indexes = SQUASHFS_XATTR_BLOCKS(*xattr_ids); /* * The computed size of the index table (len bytes) should exactly * match the table start and end points */ start = table_start + sizeof(*id_table); end = msblk->bytes_used; if (len != (end - start)) return ERR_PTR(-EINVAL); Changing the xattr_ids variable to be "usigned int" fixes the flaw on a 64-bit system. This relies on the fact the computation is widened by the unsigned long type of the sizeof operator. Casting the variable to u64 in the above macro fixes this flaw on a 32-bit system. It also means 64-bit systems do not implicitly rely on the type of the sizeof operator to widen the computation. [1] https://lore.kernel.org/lkml/000000000000cd44f005f1a0f17f@google.com/

The version of kernel installed on the remote host is prior to 5.15.93-55.139. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2024-037 advisory.

    A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service. (CVE-2022-4129)

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

    cpufreq: governor: Use kobject release() method to free dbs_data (CVE-2022-49513)

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

    ovl: Use buf flexible array for memcpy() destination (CVE-2022-49743)

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

    perf/x86/amd: fix potential integer overflow on shift of a int (CVE-2022-49748)

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

    device property: fix of node refcount leak in fwnode_graph_get_next_endpoint() (CVE-2022-49752)

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

    dmaengine: Fix double increment of client_count in dma_chan_get() (CVE-2022-49753)

    A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with     capabilities was found in the Linux kernel's OverlayFS subsystem in how a user copies a capable file from     a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges     on the system. (CVE-2023-0386)

    A memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a     user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2023-1073)

    A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the     Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel     information leak problem. (CVE-2023-1652)

    In the Linux kernel 6.0.8, there is a use-after-free in inode_cgwb_move_to_attached in fs/fs-writeback.c,     related to __list_del_entry_valid. (CVE-2023-26605)

    A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing a font->width and     font->height greater than 32 to the fbcon_set_font, since there are no checks in place, a shift-out-of-     bounds occurs, leading to undefined behavior and possible denial of service. (CVE-2023-3161)

    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)

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

    bpf: Skip invalid kfunc call in backtrack_insn (CVE-2023-52928)

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

    drm/i915: Fix potential bit_17 double-free (CVE-2023-52930)

    Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege     Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-     after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this     vulnerability to elevate its privileges to root.This issue affects Linux Kernel: from 4.14 before git     commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)

    A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited     to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate     filters in case of a perfect hashes while deleting the underlying structure which can later lead to double     freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to     root.We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. (CVE-2023-1829)

    When plain IBRS is enabled (not enhanced IBRS), the logic in spectre_v2_user_select_mitigation()     determines that STIBP is not needed. The IBRS bit implicitly protects against cross-thread branch     targetinjection. However, with legacy IBRS, the IBRS bit is cleared on returning to userspace for     performance reasons which leaves userspace threads vulnerable to cross-thread branch target injection     against which STIBP protects. (CVE-2023-1998)

    A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks.
    L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after     running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can     execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past     commit 2e7eab81425a (CVE-2022-2196)

    It has been discovered that on some AMD CPUs, the RAS (Return Address Stack, also called RAP - Return     Address Predictor - in some AMD documentation, and RSB - Return Stack Buffer - in Intel terminology) is     dynamically partitioned between non-idle threads.  This allows an attacker to control speculative     execution on the adjacent thread. (CVE-2022-27672)

    Due to a type confusion during initializations, the tun and tap sockets in the Linux Kernel have their     socket UID hardcoded to 0, i.e. root. While it will be often correct, as TUN/TAP devices require     CAP_NET_ADMIN, it may not always be the case. The socket UID may be used for network filtering and     routing, thus TUN/TAP sockets may be incorrectly managed, potentially bypassing network filters based on     UID. (CVE-2023-1076)

    The upstream bug report describes this issue as follows:

    A flaw found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The     rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user     can trigger this with rds_message_put(). Type confusion leads to `struct rds_msg_zcopy_info *info`     actually points to something else that is potentially controlled by local user. It is known how to trigger     this, which causes an OOB access, and a lock corruption. (CVE-2023-1078)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-132 advisory.

    It has been discovered that on some AMD CPUs, the RAS (Return Address Stack, also called RAP - Return     Address Predictor - in some AMD documentation, and RSB - Return Stack Buffer - in Intel terminology) is     dynamically partitioned between non-idle threads.  This allows an attacker to control speculative     execution on the adjacent thread. (CVE-2022-27672)

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

    ovl: Use buf flexible array for memcpy() destination (CVE-2022-49743)

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

    mm/uffd: fix pte marker when fork() without fork event (CVE-2022-49744)

    The upstream bug report describes this issue as follows:

    A flaw found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The     rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user     can trigger this with rds_message_put(). Type confusion leads to `struct rds_msg_zcopy_info *info`     actually points to something else that is potentially controlled by local user. It is known how to trigger     this, which causes an OOB access, and a lock corruption. (CVE-2023-1078)

    A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing a font->width and     font->height greater than 32 to the fbcon_set_font, since there are no checks in place, a shift-out-of-     bounds occurs, leading to undefined behavior and possible denial of service. (CVE-2023-3161)

    brcm_nvram_parse in drivers/nvmem/brcm_nvram.c lacks check of the return value of kzalloc() and will cause     the NULL Pointer Dereference (CVE-2023-3359)

    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)
