VUL-0: CVE-2021-29266: kernel-source: drivers/vhost/vdpa.c has a use-after-free
Last modified: 2022-05-03 12:55:32 UTC
An issue was discovered in the Linux kernel before 5.11.9. drivers/vhost/vdpa.c
has a use-after-free because v->config_ctx has an invalid value upon re-opening
a character device, aka CID-f6bbf0010ba0.
The fix commit suggests:
Fixes: 776f395004d8 ("vhost_vdpa: Support config interrupt in vdpa")
which is in 5.8-rc1 kernel. And this isn't backported to any SLE branches.
TW kernel already got the fix via 5.11.9 stable tree.
Reassigned back to security team.
Closing, as we are not affected.
