CVE-2022-50697 mrp: introduce active flags to prevent UAF when applicant uninit

In the Linux kernel, the following vulnerability has been resolved: mrp: introduce active flags to prevent UAF when applicant uninit The caller of deltimersync must prevent restarting of the timer, If we have no this synchronization, there is a small probability that the cancellation will not be...

CVE-2022-50697

CVE-2022-50697 affects the Linux kernel and relates to a race in timer cancellation that could lead to a use-after-free (UAF). The issue stems from a lack of synchronization when del_timer_sync is involved, with a syzbot crash trace showing a KASAN use-after-free in hlist_add_head and enqueue_tim...

mod_md: Apache HTTP Server: mod_md (ACME), unintended retry intervals

An integer overflow flaw has been discovered in the Apache HTTP server. The integer overflow in the case of failed ACME certificate renewal leads, after a number of failures 30 days in default configurations, to the backoff timer becoming 0. Attempts to renew the certificate then are repeated...
