Linux · Linux Kernel · CVE-2022-48863
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
The issue is related to the `dsp pipeline build()` function in the mISDN component of the Linux kernel. It involves the allocation of a `dup` pointer by `kstrdup(cfg)`, which is then updated by `strsep(&dup, "|")`. As a result, when `kfree(dup)` is called, the `dup` variable contains NULL, leading to a memory leak. This could potentially allow an attacker to cause a denial of service.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
