The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1778266904 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: samples/landlock: Fix path_list memory     leak Clang static analysis reports this error sandboxer.c:134:8: warning: Potential leak of memory pointed     to by 'path_list' ret = 0; ^ path_list is allocated in parse_path() but never freed. (CVE-2021-47654)

  - In the Linux kernel, the following vulnerability has been resolved: tty: synclink_gt: Fix null-pointer-     dereference in slgt_clean() When the driver fails at alloc_hdlcdev(), and then we remove the driver     module, we will get the following splat: [ 25.065966] general protection fault, probably for non-canonical     address 0xdffffc0000000182: 0000 [#1] PREEMPT SMP KASAN PTI [ 25.066914] KASAN: null-ptr-deref in range     [0x0000000000000c10-0x0000000000000c17] [ 25.069262] RIP: 0010:detach_hdlc_protocol+0x2a/0x3e0 [     25.077709] Call Trace: [ 25.077924] <TASK> [ 25.078108] unregister_hdlc_device+0x16/0x30 [ 25.078481]     slgt_cleanup+0x157/0x9f0 [synclink_gt] Fix this by checking whether the 'info->netdev' is a null pointer     first. (CVE-2022-49307)

  - In the Linux kernel, the following vulnerability has been resolved: ima: Fix potential memory leak in     ima_init_crypto() On failure to allocate the SHA1 tfm, IMA fails to initialize and exits without freeing     the ima_algo_array. Add the missing kfree() for ima_algo_array to avoid the potential memory leak.
    (CVE-2022-49627)

  - 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)

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.

  - usb: typec: wusb3801: fix fwnode refcount leak in wusb3801_probe() I got the following report while doing     fault injection test: OF: ERROR: memory leak, expected refcount 1 instead of 4,     of_node_get()/of_node_put() unbalanced - destroy cset entry: attach overlay node /i2c/tcpc@60/connector If     wusb3801_hw_init() fails, fwnode_handle_put() needs be called to avoid refcount leak. (CVE-2022-50825)

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