In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix memory leak in amdxdnaubufmap The amdxdnaubufmap function allocates memory for sg and internal sg table structures, but it fails to free them if subsequent operations sgalloctablefrompages or dmamapsgtable fail...

CVE-2026-45886

CVE-2026-45886: In the Linux kernel, a patch fixes the bpf_xdp_store_bytes prototype for read-only arguments. The issue caused the verifier to treat the third argument as a BPF_WRITE target when NATed map memory was read-only, resulting in a forbidden write to a read-only map. The patch adjusts t...
