CVE-2026-53200

The CVE refers to the Linux kernel KVM on ARM64 where the XN bit handling was broken when FEAT_XNX is not enabled. Specifically, a FIELD_PREP() mask used to clear XN[0] manipulated the wrong bit, unconditionally granting execute permissions. The issue is resolved by correcting the bit manipulatio...

CVE-2026-53191

CVE-2026-53191 affects the Linux kernel io_uring/net path. In bundle recv retries (with incremental mode and provided buffer rings IOU_PBUF_RING_INC), a memory handling bug caused IORING_CQE_F_BUF_MORE to be dropped during flag merge, allowing the kernel to leave a stale BUF_MORE in carried flags...

CVE-2026-53185

CVE-2026-53185 concerns the Linux kernel zram subsystem. The issue is a use-after-free in zram_bvec_write_partial(), where zram_read_page() can dispatch reads asynchronously for ZRAM_WB slots and return before the backing read completes. The caller may then operate on a buffer that is freed, risk...
