CVE-2021-47597

CVE-2021-47597 affects the Linux kernel inet_diag path handling UDP sockets. The root cause is that UDP paths did not initialize r->idiag_expires in inet_sk_diag_fill(), enabling kernel-infoleak reports observed by KMSAN. The provided connected advisories describe a chain of in-kernel data flo...

USN-6818-4: Linux kernel (HWE) vulnerabilities

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service system crash. CVE-2023-6356, CVE-2023-6535, CVE-2023-6536 It was...

UBUNTU-CVE-2024-0397

A defect was discovered in the Python “ssl” module where there is a memory race condition with the ssl.SSLContext methods “certstorestats” and “getcacerts”. The race condition can be triggered if the methods are called at the same time as certificates are loaded into the SSLContext, such as durin...

The vulnerability of the unix_stream_recv_urg() function in the implementation of AF_UNIX sockets in Linux kernels allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the unixstreamrecvurg function in the net/unix/afunix.c module, which is part of the Linux kernel’s AFUNIX socket implementation, relates to the repeated use of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...

USN-6817-3: Linux kernel vulnerabilities

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. CVE-2022-38096 Zheng Wang discovered that the Broadc...

CVE-2024-36971

A use-after-free flaw was found in the Linux kernel's network route management. This flaw allows an attacker to alter the behavior of certain network connections. Mitigation Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical...
