Important: gfs2-utils

Issue Overview: A stack overflow vulnerability was found in gfs2-utils. The hash table traversal code in metawalk.c uses alloca with an exponentially-derived size from the untrusted on-disk didepth field without bounds validation. A crafted GFS2 filesystem image with a large didepth value causes...

Amazon Linux 2 : alsa-lib (ALAS-2026-4041)

The version of alsa-lib installed on the remote host is prior to 1.1.4.1-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-4041 advisory. alsa-lib through 1.2.16.1 contains a stack buffer overflow in the sndctlasciielemidparse function that writes one byte...

Medium: alsa-lib

Issue Overview: alsa-lib through 1.2.16.1 contains a stack buffer overflow in the sndctlasciielemidparse function that writes one byte past a 64-byte buffer when parsing a name= field with 64 or more characters. Attackers can supply a long control-element identifier string through saved state fil...

CVE-2026-53921

odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. Prior to version 25.12, odhcpd's DHCPv6 IA response handler writes past the end of a fixed 512-byte stack buffer pdbuf when a single DHCPv6 REQUEST carries enough IA options to nearly exhaust the reply space. Two...

CVE-2026-55606 odhcpd: Stack buffer overread via DUID length endianness mismatch in memcmp()

odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. In versions 25.12 and prior, odhcpd's DHCPv6 self-loop detection at dhcpv6.c:720 uses a network-byte-order DUID length value directly as the memcmp size parameter. On little-endian hosts, this causes memcmp to read far...

CVE-2026-55606

The odhcpd server, used by OpenWrt in versions 25.12 and prior , is vulnerable to a stack buffer overread due to a DUID length endianness mismatch in dhcpv6.c:720. On little-endian hosts , the software uses a network-byte-order DUID length value directly as a memcmp() size parameter, allowing a s...
