CVE-2026-44687 Off-by-one error in 'harden-below-nxdomain' logic can shadow a stub/forward zone by a legitimate parent's NXDOMAIN

In NLnet Labs Unbound 1.13.2 up to and including 1.25.1, stub or forward zones where the name is below an intermediate labed below a DNSSEC signed zone could be shadowed by the intermediate label's secure NXDOMAIN answer from the parent. This is caused by an off-by-one error in...

kernel: crypto: af_alg - zero initialize memory allocated via sock_kmalloc

A flaw was found in the Linux kernel's crypto AFALG subsystem. Memory allocated via sockkmalloc for crypto user API contexts is not zero-initialized, leaving fields with garbage values. Specifically, the 'inflight' variable can contain random data, causing afalgallocareq to spuriously return -EBU...

kernel: scsi: core: Wake up the error handler when final completions race against each other

Race condition vulnerabilities were found in the Linux kernel's SCSI error handler wake-up logic. Memory ordering issues in scsidechostbusy and ordering problems in scsiehinchostfailed can cause the SCSI error handler to never wake up when command completions race against each other. This leaves...

CVE-2026-16473

A flaw was found in the sbc library BlueZ SBC codec. An off-by-one error in the SBC frame decoder allows a crafted audio payload to trigger a one-byte heap out-of-bounds read. This could allow an adjacent attacker streaming Bluetooth audio to read a single byte of adjacent heap memory...
