Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: dmaengine: xilinx: xdma: Fixed regmap maxregister The maxregister field is assigned the size of the register memory region, rather than the offset of the last register. As a result, reading from the regmap via debugfs can cause a...

Astra Linux – Vulnerability in PostgresSQL-15

Integer wraparound in several PostgreSQL libpq client library functions allows an application’s input provider or network peer to cause libpq to undersize allocations and write out-of-bounds data, involving hundreds of megabytes. This leads to a segmentation fault in the application that uses...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

Use After Free
