In the Linux kernel, the following vulnerabilities have been resolved: lib/fonts: Fixed undefined behavior in bit shifting for getdefaultfont. Shifting a signed 32-bit value by 31 bits is undefined; therefore, the significant bit was changed to unsigned. The UBSAN warning appears as follows: UBSA...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU implementation of VMWare’s paravirtual RDMA device in versions prior to 6.1.0. The issue occurs when handling a “PVRDMAREGDSRHIGH” write from the guest, and it may result in a crash of QEMU or cause undefined behavior due to the access of an uninitialized pointer...
