In the Linux kernel, the following vulnerability has been resolved: sched: sch_cake: add bounds checks to host bulk flow fairness counts Even though we fixed a logic error in the commit cited below, syzbot still managed to trigger an underflow of the per-host bulk flow counters, leading to an out of bounds memory access. To […]

First, if the goal is to use it to read or write per-netns data, this is inconsistent with how the “generic” sysctl entries are doing: directly by […]
In the Linux kernel, the following vulnerability has been resolved: rds: sysctl: rds_tcp_{rcv,snd}buf: avoid using current->nsproxy As mentioned in a previous commit of this series, using the ‘net’ structure via ‘current’ is not recommended for different reasons: – Inconsistency: getting info from the reader’s/writer’s netns vs only from the opener’s netns. – current->nsproxy can be […]
