In the Linux kernel, the following vulnerability has been resolved: x86/sev: Make enc_dec_hypercall() accept a size instead of npages enc_dec_hypercall() accepted a page count instead of a size, which forced its callers to round up. As a result, non-page aligned vaddrs caused pages to be spuriously marked as decrypted via the encryption status hypercall, which in turn caused consistent corruption of pages during live migration. Live migration requires accurate encryption status information to avoid migrating pages from the wrong perspective.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1771239384 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: block, bfq: fix uaf for bfqq in     bfq_exit_icq_bfqq Commit 64dc8c732f5c (block, bfq: fix possible uaf for 'bfqq->bic') will access     'bic->bfqq' in bic_set_bfqq(), however, bfq_exit_icq_bfqq() can free bfqq first, and then call     bic_set_bfqq(), which will cause uaf. Fix the problem by moving bfq_exit_bfqq() behind bic_set_bfqq().

  - In the Linux kernel, the following vulnerability has been resolved: wifi: ath10k: Delay the unmapping of     the buffer On WCN3990, we are seeing a rare scenario where copy engine hardware is sending a copy complete     interrupt to the host driver while still processing the buffer that the driver has sent, this is leading     into an SMMU fault triggering kernel panic. This is happening on copy engine channel 3 (CE3) where the     driver normally enqueues WMI commands to the firmware. Upon receiving a copy complete interrupt, host     driver will immediately unmap and frees the buffer presuming that hardware has processed the buffer. In     the issue case, upon receiving copy complete interrupt, host driver will unmap and free the buffer but     since hardware is still accessing the buffer (which in this case got unmapped in parallel), SMMU hardware     will trigger an SMMU fault resulting in a kernel panic. In order to avoid this, as a work around, add a     delay before unmapping the copy engine source DMA buffer. This is conditionally done for WCN3990 and only     for the CE3 channel where issue is seen.

  - In the Linux kernel, the following vulnerability has been resolved: tcp: fix a signed-integer-overflow bug     in tcp_add_backlog() The type of sk_rcvbuf and sk_sndbuf in struct sock is int, and in tcp_add_backlog(),     the variable limit is caculated by adding sk_rcvbuf, sk_sndbuf and 64 * 1024, it may exceed the max value     of int and overflow. This patch reduces the limit budget by halving the sndbuf to solve this issue since     ACK packets are much smaller than the payload. (CVE-2022-50865)

  - In the Linux kernel, the following vulnerability has been resolved: block, bfq: fix uaf for bfqq in     bic_set_bfqq() After commit 64dc8c732f5c (block, bfq: fix possible uaf for 'bfqq->bic'), bic->bfqq will     be accessed in bic_set_bfqq(), however, in some context bic->bfqq will be freed, and bic_set_bfqq() is     called with the freed bic->bfqq. Fix the problem by always freeing bfqq after bic_set_bfqq().

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

  - x86/sev: Make enc_dec_hypercall() accept a size instead of npages enc_dec_hypercall() accepted a page     count instead of a size, which forced its callers to round up. As a result, non-page aligned vaddrs caused     pages to be spuriously marked as decrypted via the encryption status hypercall, which in turn caused     consistent corruption of pages during live migration. Live migration requires accurate encryption status     information to avoid migrating pages from the wrong perspective. (CVE-2023-53996)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-356 advisory.

    An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

    nftables out-of-bounds read in nf_osf_match_one() (CVE-2023-39189)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the     fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds     read by setting the size fields with a value beyond the array boundaries, leading to a crash or     information disclosure. (CVE-2023-39192)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the     flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds     read, leading to a crash or information disclosure. (CVE-2023-39193)

    An integer overflow in kmalloc_reserve() in the Linux kernel may allow a local user to crash the system,     or in some cases obtain code execution in kernel space. (CVE-2023-42752)

    The upstream commit describes this issue as follows:

    The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can lead to the use of wrong     `CIDR_POS(c)` for calculating array offsets, which can lead to integer underflow. As a result, it leads to     slab out-of-bound access. (CVE-2023-42753)

    A flaw was found in rsvp_change(). The root cause is an slab-out-of-bound access, but since the offset to     the original pointer is an `unsign int` fully controlled by users, the behavior is usually a wild pointer     access. (CVE-2023-42755)

    An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel     before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)

    A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control)     component can be exploited to achieve local privilege escalation.

    If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing     curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in     update_vf(). This leaves a dangling pointer that can cause a use-after-free.

    We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f. (CVE-2023-4623)

    A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to     achieve local privilege escalation.

    When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free     in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in     agg_dequeue().

    We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8. (CVE-2023-4921)

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

    netfilter: nftables: exthdr: fix 4-byte stack OOB write

    If priv->len is a multiple of 4, then dst[len / 4] can write pastthe destination array which leads to     stack corruption.

    This construct is necessary to clean the remainder of the registerin case ->len is NOT a multiple of the     register size, so make itconditional just like nft_payload.c does.

    The bug was added in 4.1 cycle and then copied/inherited whentcp/sctp and ip option support was added.
