CVE-2022-25265
This can cause execution of bytes located in supposedly non-executable regions of a file.
HIGH 7.8EPSS 1.05%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.05%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel through 5.16.10, certain binary files may have the exec-all attribute if they were built in approximately 2003 (e.g., with GCC 3.2.2 and Linux kernel 2.4.20). This can cause execution of bytes located in supposedly non-executable regions of a file.
