OESA-2024-1242 (CVE-2023-52435)
Vulnerability from osv_openeuler – Published: 2024-03-01 11:06 – Updated: 2026-08-06 11:06 – Source websiteThe Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
net: prevent mss overflow in skb_segment()
Once again syzbot is able to crash the kernel in skb_segment() [1]
GSO_BY_FRAGS is a forbidden value, but unfortunately the following computation in skb_segment() can reach it quite easily :
mss = mss * partial_segs;
65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to a bad final result.
Make sure to limit segmentation so that the new mss value is smaller than GSO_BY_FRAGS.
