- Summary
- ASoC: rsnd: Fix potential out-of-bounds access of component_dais[]
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ASoC: rsnd: Fix potential out-of-bounds access of component_dais[]
componentdais[RSNDMAXCOMPONENT] is initially zero-initialized and later populated in rsnddaiofnode(). However, the existing boundary check: if (i >= RSNDMAXCOMPONENT)
does not guarantee that the last valid element remains zero. As a result, the loop can rely on componentdais[RSNDMAX_COMPONENT] being zero, which may lead to an out-of-bounds access.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
