efiguard-detected
efiguard-detect dumbest possible way to check if EfiGuard killed your patchguard or not. how it works efiguard leaves a SetVariable backdoor at runtime - we just poke it from usermode asking to read 2 bytes at ntoskrnl base. if we get back MZ - the backdoor is alive, efiguard did its thing, pg is...
Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: efivarfs: forces RO when remounting if SetVariable is not supported If SetVariable at runtime is not supported by the firmware, we never assign a callback for that function. At the same time, we mount efivarfs as RO so that no on...
curl: Integer Underflow in src/var.c
Summary: A potential Integer Underflow vulnerability was identified in the setvariable function within src/var.c. the flaw occurs during the calculation of the variable content length clen when a byte range is specified. specifically, the code fails to validate if startoffset is greater than...

kernel: efivarfs: force RO when remounting if SetVariable is not supported
A flaw was found in the Linux kernel, which involves the improper handling of the efivarfs filesystem when the firmware does not support the SetVariable function at runtime. Specifically, even if efivarfs is initially mounted as read-only RO, it can be remounted as read-write RW without checking ...
