Description

In the Linux kernel, the following vulnerability has been resolved: s390/uv: Don't call folio_wait_writeback() without a folio reference folio_wait_writeback() requires that no spinlocks are held and that a folio reference is held, as documented. After we dropped the PTL, the folio could get freed concurrently. So grab a temporary reference.

Affected configurations

• linux linux kernel (>= 5.7 < 6.1.103) • linux linux kernel (>= 6.2 < 6.6.44) • linux linux kernel (>= 6.7 < 6.10.3)
