Vulnerability Title
wifi: ath11k: Fix SKB corruption in REO destination ring
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: Fix SKB corruption in REO destination ring While running traffics for a long time, randomly an RX descriptor filled with value "0" from REO destination ring is received. This descriptor which is invalid causes the wrong SKB (SKB stored in the IDR lookup with buffer id "0") to be fetched which in turn causes SKB memory corruption issue and the same leads to crash after some time. Changed the start id for idr allocation to "1" and the buffer id "0" is reserved for error validation. Introduced Sanity check to validate the descriptor, before processing the SKB. Crash Signature : Unable to handle kernel paging request at virtual address 3f004900 PC points to "b15_dma_inv_range+0x30/0x50" LR points to "dma_cache_maint_page+0x8c/0x128".
