| Vector | AV:L/AC:L/Au:S/C:C/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains an issue within the
widen imprecise scalars() function related to stack depth accounting. The function does not properly account for differences in allocated stack depth between ancestor states in the explored states tree, potentially leading to out-of-bounds access when accessing bpf verifier state->frame[*]->stack. The issue arises when subsequent calls to a function allocate different amounts of stack space, and the function attempts to access stack data based on an incorrect stack depth. The function find prev entry() and push stack() are used prior to calling widen imprecise scalars().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
