In the Linux kernel, the following vulnerability has been resolved: mISDN: Fix memory leak in dsp_pipeline_build() dsp_pipeline_build() allocates dup pointer by kstrdup(cfg), but then it updates dup variable by strsep(&dup, "|"). As a result when it calls kfree(dup), the dup variable contains NULL. Found by Linux Driver Verification project (linuxtesting.org) with SVACE. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: mISDN: corrige la pérdida de memoria en dsp_pipeline_build() dsp_pipeline_build() asigna el puntero dup mediante kstrdup(cfg), pero luego actualiza la variable dup mediante strsep(&dup, "|"). Como resultado, cuando llama a kfree(dup), la variable dup contiene NULL.

CVSS: 7.0EPSS: 0%CPEs: 6EXPL: 0CVE-2022-48858 – net/mlx5: Fix a race on command flush flow
https://notcve.org/view.php?id=CVE-2022-48858
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix a race on command flush flow Fix a refcount use after free warning due to a race on command entry. Such race occurs when one of the commands releases its last refcount and frees its index and entry while another process running command flush flow takes refcount to this command entry. The process which handles commands flush may see this command as needed to be flushed if the other process released its refcount but didn't release the index yet. Fix it by adding the needed spin lock. It fixes the following warning trace: refcount_t: addition on 0; use-after-free.

In the Linux kernel, the following vulnerability has been resolved: NFC: port100: fix use-after-free in port100_send_complete Syzbot reported UAF in port100_send_complete(). The root case is in missing usb_kill_urb() calls on error handling path of ->probe function. port100_send_complete() accesses devm allocated memory which will be freed on probe failure.
