net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...

CVE-2026-39820 Well-crafted inputs reaching ParseAddress, ParseAddressList, and ParseDate were able to trigger excessive CPU...

kernel: scsi: qla2xxx: Completely fix fcport double free

A flaw was found in the Linux kernel's qla2xxx SCSI driver. An issue exists where a Fibre Channel port fcport object can be freed twice due to an error in the qla2x00elsdcmdspfree function. This double free vulnerability can lead to memory corruption, potentially causing system instability or a...

kernel: RDMA/rxe: Fix double free in rxe_srq_from_init

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the rxe driver. An error in the rxesrqfrominit function's memory management can lead to a double free vulnerability. This occurs when an attempt to copy data to user space fails, causing the sam...

SUSE CVE-2026-14164

A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filteredbuf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of...

CVE-2026-10653

The Zephyr netbuf library lib/netbuf/buf.c manipulated both of its reference counts -- the per-header buf-ref and the per-data-block refcount at the start of each variable/heap data allocation -- with plain non-atomic C operators buf-ref++, if --buf-ref 0, if --refcount. The API is documented as...

CVE-2026-10653

The CVE-2026-10653 issue affects the Zephyr net_buf library (lib/net_buf/buf.c). It relies on non-atomic operations for two reference counters: the per-header buf->ref and the per-data-block ref_count. Under true concurrency, two independent unrefs can observe the same prior value and both tre...
