CVE-2023-42755 SUSE CVE security@suse.de SUSE Security Team SUSE CVE-2023-42755 Interim 1 2 2023-10-05T23:18:18Z current 2023-09-26T23:18:20Z 2023-10-05T23:18:18Z cve-database/bin/generate-cvrf-cve.pl 2020-12-27T01:00:00Z CVE-2023-42755 A flaw was found in the IPv4 Resource Reservation Protocol (RSVP) classifier in the Linux kernel. The xprt pointer may go beyond the linear part of the skb, leading to an out-of-bounds read in the `rsvp_classify` function. This issue may allow a local user to crash the system and cause a denial of service.
