CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-52676 – bpf: Guard stack limits against 32bit overflow
https://notcve.org/view.php?id=CVE-2023-52676
In the Linux kernel, the following vulnerability has been resolved: bpf: Guard stack limits against 32bit overflow This patch promotes the arithmetic around checking stack bounds to be done in the 64-bit domain, instead of the current 32bit. The arithmetic implies adding together a 64-bit register with a int offset. The register was checked to be below 1<<29 when it was variable, but not when it was fixed. The offset either comes from an instruction (in which case it is 16 bit), from another register (in which case the caller checked it to be below 1<<29 [1]), or from the size of an argument to a kfunc (in which case it can be a u32 [2]). Between the register being inconsistently checked to be below 1<<29, and the offset being up to an u32, it appears that we were open to overflowing the `int`s which were currently used for arithmetic.

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix potential sta-link leak When a station is allocated, links are added but not set to valid yet (e.g. during connection to an AP MLD), we might remove the station without ever marking links valid, and leak them. Fix that.
