CBL Mariner 2.0 Security Update: CBL-Mariner Releases (CVE-2026-39979)

The version of CBL-Mariner Releases installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2026-39979 advisory. - jq is a command-line JSON processor. In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5...

CVE-2026-31664

A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises because the buildpolexpire function does not clear trailing padding bytes within the xfrmuserpolexpire structure. Consequently, these uninitialized padding bytes, which contain kernel heap memory contents, are sent t...

CVE-2026-31649

A flaw was found in the Linux kernel's stmmac network driver. An integer underflow vulnerability in the jumbofrm function, when processing specially crafted fragmented network packets, can lead to a memory disclosure and potential memory corruption. This issue allows an attacker to read arbitrary...

CVE-2026-31614

A flaw was found in the Linux kernel's Server Message Block SMB client. An untrusted server can exploit an out-of-bounds read vulnerability within the checkwsleas function. This flaw allows the server to read up to 8 bytes beyond the intended memory boundary, leading to information disclosure. Th...

CVE-2026-31617

A flaw was found in the Linux kernel's USB Network Control Model NCM gadget driver. A malicious USB host could exploit an integer underflow vulnerability when processing Network Transfer Block NTB headers. This allows the host to manipulate internal data pointers, causing adjacent kernel memory t...

CVE-2026-41079

OpenPrinting CUPS (prior to 2.4.17) is vulnerable to a network-adjacent attacker who can send a crafted SNMP response to the CUPS SNMP backend, causing an out-of-bounds read of up to 176 bytes past a stack buffer. The leaked memory is interpreted from UTF-16 to UTF-8 and stored as printer supply ...

CVE-2026-31617

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fncm: validate minimum blocklen in ncmunwrapntb The blocklen read from the host-supplied NTB header is checked against ntbmax but has no lower bound. When blocklen is smaller than opts-ndpsize, the bounds check of:...

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: 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...

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...
