CVE-2026-31649

The CVE-2026-31649 issue affects the Linux kernel’s stmmac driver, where jumbo_frm() can underflow when processing fragmented packets. If nopaged_len is small but skb->len is large, len = nopaged_len - buf_len (with buf_len clamped to min(nopaged_len, bmax)) can still yield a large unsigned va...

CVE-2026-5367

A flaw was found in OVN Open Virtual Network. A remote attacker, by sending crafted DHCPv6 Dynamic Host Configuration Protocol for IPv6 SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet. This out-of-bounds read can lead to the...

CVE-2026-33317

OP-TEE is affected by a vulnerability in PKCS#11 support: versions 3.13.0–4.10.0 contain missing checks in entry_get_attribute_value() (ta/pkcs11/src/object.c), enabling an out-of-bounds read from the PKCS#11 TA heap and potentially memory corruption when combined with an OOB read. This can allow...

CVE-2026-33317 OP-TEE: PKCS#11 TA out-of-bounds read and memory disclosure

OP-TEE is a Trusted Execution Environment TEE designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. In versions 3.13.0 through 4.10.0, missing checks in entrygetattributevalue in ta/pkcs11/src/object.c can lead to out-of-bounds read from...

Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: jq (UTSA-2026-014278)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-014278 advisory. jq is a command-line JSON processor. In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5f, the jvparsesized API in libjq accepts a counted buffer with an...

CVE-2026-31464

A flaw was found in the Linux kernel's scsi: ibmvfc driver. A malicious or compromised Virtual I/O VIO server can exploit this by sending a crafted response during target discovery. This response can cause an out-of-bounds memory access, leading to the disclosure of sensitive kernel memory...

CVE-2026-5928

A flaw was found in glibc GNU C Library. When the ungetwc function is called on a file stream using wide characters with specific overlapping single-byte and multi-byte encodings, it may attempt to read data outside of its allocated buffer. This can lead to the unintentional disclosure of sensiti...
