Description
In the Linux kernel, the following vulnerability has been resolved:
regmap: maple: free entry on mas_store_gfp() failure
regcache_maple_write() allocates a new block ('entry') to merge
adjacent ranges and then stores it with mas_store_gfp().
When mas_store_gfp() fails, the new 'entry' remains allocated and
is never freed, leaking memory.
Free 'entry' on the failure path; on success continue freeing the
replaced neighbor blocks ('lower', 'upper').
Affected configurations
• linux linux kernel (>= 6.4 < 6.6.124)
• linux linux kernel (>= 6.7 < 6.12.70)
• linux linux kernel (>= 6.13 < 6.18.10)
• linux linux kernel 6.19
