CVE-2026-90043 zram: fix slot lock bit position on big-endian 64-bit

In the Linux kernel, the following vulnerability has been resolved: zram: fix slot lock bit position on big-endian 64-bit The slot lock is a bit operation on the whole lock word, which flags and actime alias as two u32s. On little-endian the lock bit lands in the position ZRAMENTRYLOCK reserves i...

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...
