CVE-2023-53402

CVE-2023-53402 affects the Linux kernel, specifically the printk debugfs path. The root cause is a memory leak in kernel/printk/index.c when using debugfs_lookup() without a matching dput(). The documented fix replaces the sequence with debugfs_lookup_and_remove(), handling the logic and preventi...

CVE-2023-53402 kernel/printk/index.c: fix memory leak with using debugfs_lookup()

In the Linux kernel, the following vulnerability has been resolved: kernel/printk/index.c: fix memory leak with using debugfslookup When calling debugfslookup the result must have dput called on it, otherwise the memory will leak over time. To make things simpler, just call debugfslookupandremove...

CVE-2022-50400

The CVE-2022-50400 issue concerns the Linux kernel greybus: audio_helper code, where debugfs usage was removed due to incorrect handling that could leak memory and even erase all debugfs entries. The fix is to remove all debugfs logic from the audio_helper code; if needed later, a fix for the inc...

CVE-2023-53390

CVE-2023-53390 affects the Linux kernel (drivers: base: dd) where a call to debugfs_lookup() leaked memory because the result wasn’t dput()-ed. The fix uses debugfs_lookup_and_remove() to handle lookup and cleanup atomically, preventing the leak. Impact described: potential unbounded memory growt...
