kernel: Stack corruption while reading /proc/keys when gcc stack protector is enabled

It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks...

The vulnerability of the patch offset2lib in the Linux operating system’s kernel allows a hacker to gain access to the stack protection mechanism.

The vulnerability of patch offset2lib in Linux operating systems arises from the minimal memory range between the upper boundary of the stack and the PIE binary code segment, which is located in memory starting at 0x80000000. This occurs when the RLIMITSTACK parameter is set to RLIMINFINITY, and ...
