Linux eBPF ALU32 32-bit Invalid Bounds Tracking Local Privilege Escalation Exploit

Linux kernels from 5.7-rc1 prior to 5.13-rc4, 5.12.4, 5.11.21, and 5.10.37 are vulnerable to a bug in the eBPF verifier's verification of ALU32 operations in the scalar32minmaxand function when performing AND operations, whereby under certain conditions the bounds of a 32 bit register would not b...
