Description

In the Linux kernel, the following vulnerability has been resolved: regulator: gpio: Fix the out-of-bounds access to drvdata::gpiods drvdata::gpiods is supposed to hold an array of 'gpio_desc' pointers. But the memory is allocated for only one pointer. This will lead to out-of-bounds access later in the code if 'config::ngpios' is > 1. So fix the code to allocate enough memory to hold 'config::ngpios' of GPIO descriptors. While at it, also move the check for memory allocation failure to be below the allocation to make it more readable.

• linux linux kernel (>= 5.1 < 5.4.296) • linux linux kernel (>= 5.5 < 5.10.240) • linux linux kernel (>= 5.11 < 5.15.187) • linux linux kernel (>= 5.16 < 6.1.144) • linux linux kernel (>= 6.2 < 6.6.97) • linux linux kernel (>= 6.7 < 6.12.37) • linux linux kernel (>= 6.13 < 6.15.6) • linux linux kernel 6.16 • debian debian linux 11.0
