Kernel crash due to out-of-bounds memory accesses in process_vm_readv().It was discovered that the implementation of process_vm_readv() system call could try to access memory outside of the structures it was processing in certain cases. A local unprivileged user could use this vulnerability to crash the system.
quotaoff operation executed in a container could get stuck in D state.
Certain operations with an empty ploop image could lead to its unexpected growth.
Incomplete fix for PSBM-100575: reading of /proc/bc/resources line by line would never end.
memcg: memory corruption caused by writing beyond the end of shrinker_map structure.
ixgbe: lots of warnings in the system log due to incorrect check for firmware errors.
ploop: kernel crashes when processing discard requests for ploop images in raw format.
scsi: printing lots of messages about rejected I/O causes a hard lockup and a kernel crash.
Kernel crash in shrink_slab() when trying to mount an image with a broken ext4 file system.
Reading of /proc/bc/resources line by line would never end: no end of file was reported.
Potential kernel crash in __radix_tree_insert() when fscache is used for NFS mounts.
sunrpc: potential kernel crash in bc_svc_process().
A bug in ploop prevented recovery of corrupted ploop images.
The minimum amount of reserved free memory (vm.min_free_kbytes) was set too high by default.
kvm: potential system hang due to an error in mmu_shrink_scan().
Processes could get stuck in copy_net_ns() forever.
