In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Fix handling of XN0 when !FEATXNX XN has already been extracted from its bitfield position so using FIELDPREP on the mask that clears XN0 is completely broken, having the effect of unconditionally granting execute...

CVE-2026-53191

The CVE affects the Linux kernel io_uring net path in bundle recv retries. The bug arises when merging cflags during io_recv_finish(): IORING_CQE_F_BUF_MORE was not included in CQE_F_MASK, so the buf-more flag could be dropped or mis-carryed across iterations, causing userspace to advance the rin...
