CVE-2026-43285

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the slab memory allocator where get from any partial() may be called in an NMI (Non-Maskable Interrupt) context. This leads to an inconsistent lock state because current->mems allowed seq is a seqcount spinlock t, which is not NMI-safe. This can result in a deadlock if the read path interrupts the write-side critical section.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
