In the Linux kernel, the following vulnerability has been resolved:
net: sched: sch: Bounds check priority
Nothing was explicitly bounds checking the priority index used to access
clpriop[]. WARN and bail out early if it's pathological. Seen with GCC 13:
../net/sched/sch_htb.c: In function 'htb_activate_prios':
../net/sched/sch_htb.c:437:44: warning: array subscript [0, 31] is outside array bounds of 'struct htb_prio[8]' [-Warray-bounds=]
437 | if (p->inner.clprio[prio].feed.rb_node)
| ~~~~~~~~~~~~~~~^~~~~~
../net/sched/sch_htb.c:131:41: note: while referencing 'clprio'
131 | struct htb_prio clprio[TC_HTB_NUMPRIO];
| ^~~~~~
