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

  - lib/alloc_tag: do not acquire non-existent lock in alloc_tag_top_users() alloc_tag_top_users() attempts to     lock alloc_tag_cttype->mod_lock even when the alloc_tag_cttype is not allocated because: 1) alloc tagging     is disabled because mem profiling is disabled (!alloc_tag_cttype) 2) alloc tagging is enabled, but not yet     initialized (!alloc_tag_cttype) 3) alloc tagging is enabled, but failed initialization (!alloc_tag_cttype     or IS_ERR(alloc_tag_cttype)) In all cases, alloc_tag_cttype is not allocated, and therefore     alloc_tag_top_users() should not attempt to acquire the semaphore. This leads to a crash on memory     allocation failure by attempting to acquire a non-existent semaphore: Oops: general protection fault,     probably for non-canonical address 0xdffffc000000001b: 0000 [#3] SMP KASAN NOPTI KASAN: null-ptr-deref in     range [0x00000000000000d8-0x00000000000000df] CPU: 2 UID: 0 PID: 1 Comm: systemd Tainted: G D 6.16.0-rc2     #1 VOLUNTARY Tainted: [D]=DIE Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS     1.16.2-debian-1.16.2-1 04/01/2014 RIP: 0010:down_read_trylock+0xaa/0x3b0 Code: d0 7c 08 84 d2 0f 85 a0 02     00 00 8b 0d df 31 dd 04 85 c9 75 29 48 b8 00 00 00 00 00 fc ff df 48 8d 6b 68 48 89 ea 48 c1 ea 03 <80> 3c     02 00 0f 85 88 02 00 00 48 3b 5b 68 0f 85 53 01 00 00 65 ff RSP: 0000:ffff8881002ce9b8 EFLAGS: 00010016     RAX: dffffc0000000000 RBX: 0000000000000070 RCX: 0000000000000000 RDX: 000000000000001b RSI:

Before     the commit, the issue occurred only when it failed to allocate and initialize alloc_tag_cttype or if a     memory allocation fails before alloc_tag_init() is called. After the commit, it can be easily triggered     when memory profiling is compiled but disabled at boot. To properly determine whether alloc_tag_init() has     been called and its data structures initialized, verify that alloc_tag_cttype is a valid pointer before     acquiring the semaphore. If the variable is NULL or an error value, it has not been properly initialized.
    In such a case, just skip and do not attempt to acquire the semaphore. [harry.yoo@oracle.com: v3]     (CVE-2025-38517)
