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 remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-587.el9 build changelog.

  - In the Linux kernel, the following vulnerability has been resolved: io_uring: prevent opcode speculation     sqe->opcode is used for different tables, make sure we santitise it against speculations. (CVE-2025-21863)

  - A use-after-free flaw was found in the Linux kernel's SGI GRU driver in the way the first     gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the     gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate     their privileges on the system. (CVE-2022-3424)

  - In the Linux kernel, the following vulnerability has been resolved: tracing/histograms: Fix memory leak     problem This reverts commit 46bbe5c671e06f070428b9be142cc4ee5cedebac. As commit 46bbe5c671e0 (tracing:
    fix double free) said, the double free problem reported by clang static analyzer is: > In     parse_var_defs() if there is a problem allocating > var_defs.expr, the earlier var_defs.name is freed. >     This free is duplicated by free_var_defs() which frees > the rest of the list. However, if there is a     problem allocating N-th var_defs.expr: + in parse_var_defs(), the freed 'earlier var_defs.name' is     actually the N-th var_defs.name; + then in free_var_defs(), the names from 0th to (N-1)-th are freed; IF     ALLOCATING PROBLEM HAPPENED HERE!!! -+ \ | 0th 1th (N-1)-th N-th V     +-------------+-------------+-----+-------------+----------- var_defs: | name | expr | name | expr | ... |     name | expr | name | /// +-------------+-------------+-----+-------------+----------- These two frees     don't act on same name, so there was no double free problem before. Conversely, after that commit, we     get a memory leak problem because the above N-th var_defs.name is not freed. If enable     CONFIG_DEBUG_KMEMLEAK and inject a fault at where the N-th var_defs.expr allocated, then execute on shell     like: $ echo 'hist:key=call_site:val=$v1,$v2:v1=bytes_req,v2=bytes_alloc' > \     /sys/kernel/debug/tracing/events/kmem/kmalloc/trigger Then kmemleak reports: unreferenced object     0xffff8fb100ef3518 (size 8): comm bash, pid 196, jiffies 4295681690 (age 28.538s) hex dump (first 8     bytes): 76 31 00 00 b1 8f ff ff v1...... backtrace: [<0000000038fe4895>] kstrdup+0x2d/0x60     [<00000000c99c049a>] event_hist_trigger_parse+0x206f/0x20e0 [<00000000ae70d2cc>]     trigger_process_regex+0xc0/0x110 [<0000000066737a4c>] event_trigger_write+0x75/0xd0 [<000000007341e40c>]     vfs_write+0xbb/0x2a0 [<0000000087fde4c2>] ksys_write+0x59/0xd0 [<00000000581e9cdf>]     do_syscall_64+0x3a/0x80 [<00000000cf3b065c>] entry_SYSCALL_64_after_hwframe+0x46/0xb0 (CVE-2022-49648)

  - In the Linux kernel, the following vulnerability has been resolved: security/keys: fix slab-out-of-bounds     in key_task_permission KASAN reports an out of bounds read: BUG: KASAN: slab-out-of-bounds in __kuid_val     include/linux/uidgid.h:36 BUG: KASAN: slab-out-of-bounds in uid_eq include/linux/uidgid.h:63 [inline] BUG:

It can be reproduced by following     these steps(more details [1]): 1. Obtain more than 32 inputs that have similar hashes, which ends with the     pattern '0xxxxxxxe6'. 2. Reboot and add the keys obtained in step 1. The reproducer demonstrates how this     issue happened: 1. In the search_nested_keyrings function, when it iterates through the slots in a     node(below tag ascend_to_node), if the slot pointer is meta and node->back_pointer != NULL(it means a     root), it will proceed to descend_to_node. However, there is an exception. If node is the root, and one of     the slots points to a shortcut, it will be treated as a keyring. 2. Whether the ptr is keyring decided by     keyring_ptr_is_keyring function. However, KEYRING_PTR_SUBTYPE is 0x2UL, the same as     ASSOC_ARRAY_PTR_SUBTYPE_MASK. 3. When 32 keys with the similar hashes are added to the tree, the ROOT has     keys with hashes that are not similar (e.g. slot 0) and it splits NODE A without using a shortcut. When     NODE A is filled with keys that all hashes are xxe6, the keys are similar, NODE A will split with a     shortcut. Finally, it forms the tree as shown below, where slot 6 points to a shortcut. NODE A     +------>+---+ ROOT | | 0 | xxe6 +---+ | +---+ xxxx | 0 | shortcut : : xxe6 +---+ | +---+ xxe6 : : | | |     xxe6 +---+ | +---+ | 6 |---+ : : xxe6 +---+ +---+ xxe6 : : | f | xxe6 +---+ +---+ xxe6 | f | +---+ 4. As     mentioned above, If a slot(slot 6) of the root points to a shortcut, it may be mistakenly transferred to a     key*, leading to a read out-of-bounds read. To fix this issue, one should jump to descend_to_node if the     ptr is a shortcut, regardless of whether the node is root or not.

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 Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-21962 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: cifs: Fix integer overflow while     processing closetimeo mount option User-provided mount parameter closetimeo of type u32 is intended to     have an upper limit, but before it is validated, the value is converted from seconds to jiffies which can     lead to an integer overflow.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (bookworm), these problems have been fixed in     version 6.1.133-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
