- Summary
- CVE-2026-89877 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
media: saa7164: fix cleanup on resource allocation failure
saa7164_dev_setup() adds the device to the global saa7164_devlist before requesting the PCI BAR memory regions.
If get_resources() fails, saa7164_dev_setup() decrements the device count and returns an error, but leaves the device on saa7164_devlist. The probe error path then frees the device, leaving a dangling entry on the global list.
Reuse the existing MMIO mapping error path to remove the device from saa7164_devlist and decrement the device count before returning.
Also release BAR0 if it was successfully requested but the BAR2 request fails.
