kernel: zram: fix use-after-free in zram_bvec_write_partial()

A flaw was found in the Linux kernel, specifically within the zram module. This vulnerability is a use-after-free error, where the system attempts to use a piece of memory after it has been freed. This occurs when the zrambvecwritepartial function allows an asynchronous read to write into a page...

CVE-2026-90043

CVE-2026-90043 affects the zram module in the Linux kernel on 64-bit big-endian systems. The root cause is a bit-position aliasing bug: the slot lock bit is computed over the entire __lock word, where flags and ac_time alias as two u32 values. On big-endian, the lock bit lands in the ac_time half...
