- Summary
- CVE-2026-74733 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
gpio: pca953x: fix pca953xirqbussyncunlock regmap lock
Locking is disabled in the regmap config as this driver uses its own lock. This means that all calls to regmap functions (read or write) must hold the i2clock. The function pca953xirqbussync_unlock() did not do this, and it was therefore possible that multiple threads could cause an incorrect register to be read/written.
A previous patch partly fixed this, but only protected the write to the interrupt mask register, and not the read from the direction register.
