CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-35860 – bpf: support deferring bpf_link dealloc to after RCU grace period
https://notcve.org/view.php?id=CVE-2024-35860
In the Linux kernel, the following vulnerability has been resolved: bpf: support deferring bpf_link dealloc to after RCU grace period BPF link for some program types is passed as a "context" which can be used by those BPF programs to look up additional information. E.g., for multi-kprobes and multi-uprobes, link is used to fetch BPF cookie values. Because of this runtime dependency, when bpf_link refcnt drops to zero there could still be active BPF programs running accessing link data. This patch adds generic support to defer bpf_link dealloc callback to after RCU GP, if requested. This is done by exposing two different deallocation callbacks, one synchronous and one deferred. If deferred one is provided, bpf_link_free() will schedule dealloc_deferred() callback to happen after RCU GP. BPF is using two flavors of RCU: "classic" non-sleepable one and RCU tasks trace one. The latter is used when sleepable BPF programs are used. bpf_link_free() accommodates that by checking underlying BPF program's sleepable flag, and goes either through normal RCU GP only for non-sleepable, or through RCU tasks trace GP *and* then normal RCU GP (taking into account rcu_trace_implies_rcu_gp() optimization), if BPF program is sleepable. We use this for multi-kprobe and multi-uprobe links, which dereference link during program run. • https://git.kernel.org/stable/c/0dcac272540613d41c05e89679e4ddb978b612f1 https://git.kernel.org/stable/c/876941f533e7b47fc69977fc4551c02f2d18af97 https://git.kernel.org/stable/c/5d8d447777564b35f67000e7838e7ccb64d525c8 https://git.kernel.org/stable/c/1a80dbcb2dbaf6e4c216e62e30fa7d3daa8001ce •

https://notcve.org/view.php?id=CVE-2024-35859
In the Linux kernel, the following vulnerability has been resolved: block: fix module reference leakage from bdev_open_by_dev error path At the time bdev_may_open() is called, module reference is grabbed already, hence module reference should be released if bdev_may_open() failed. This problem is found by code review. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: bloquear: reparar la fuga de referencia del módulo de la ruta de error bdev_open_by_dev. En el momento en que se llama a bdev_may_open(), la referencia del módulo ya está tomada, por lo tanto, la referencia del módulo debe liberarse si bdev_may_open() fallo. Este problema se encuentra mediante la revisión del código. • https://git.kernel.org/stable/c/ed5cc702d311c14b653323d76062b0294effa66e https://git.kernel.org/stable/c/0e9327c67410b129bf85e5c3a5aaea518328636f https://git.kernel.org/stable/c/9617cd6f24b294552a817f80f5225431ef67b540 •

In the Linux kernel, the following vulnerability has been resolved: net: bcmasp: fix memory leak when bringing down interface When bringing down the TX rings we flush the rings but forget to reclaimed the flushed packets. This leads to a memory leak since we do not free the dma mapped buffers. This also leads to tx control block corruption when bringing down the interface for power management. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: bcmasp: corrige la pérdida de memoria al desactivar la interfaz. Al desactivar los anillos TX, los limpiamos pero nos olvidamos de recuperar los paquetes eliminados. • https://git.kernel.org/stable/c/490cb412007de593e07c1d3e2b1ec4233886707c https://git.kernel.org/stable/c/09040baf8779ad880e0e0d0ea10e57aa929ef3ab https://git.kernel.org/stable/c/2389ad1990163d29cba5480d693b4c2e31cc545c https://git.kernel.org/stable/c/9f898fc2c31fbf0ac5ecd289f528a716464cb005 •
