Page history
Changes are dated when recorded; day views use the last saved version from that UTC day, and citations stay fixed.
CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.
No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

apparmor: policy_int make sure list heads are initialized before fail path
In the Linux kernel, the following vulnerability has been resolved:
apparmor: policy_int make sure list heads are initialized before fail path
If profile create fails before policy_init is complete the list heads
are not properly initialized causing profile_free() sanity checks to
trigger the following splat.
AppArmor WARN aa_policy_destroy: (((!list_empty(&policy->profiles) && (&policy->profiles)->prev != ((void *) 0x122 + (0xdead000000000000UL))))):
