Synopsis

The remote CentOS host is missing one or more security updates for bpftool.

Description

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-435.el9 build changelog.

 - Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
 (CVE-2023-52466)

 - In the Linux kernel, the following vulnerability has been resolved: thermal: core: Fix NULL pointer dereference in zone registration error path If device_register() in thermal_zone_device_register_with_trips() returns an error, the tz variable is set to NULL and subsequently dereferenced in kfree(tz->tzp). Commit adc8749b150c (thermal/drivers/core: Use put_device() if device_register() fails) added the tz = NULL assignment in question to avoid a possible double-free after dropping the reference to the zone device. However, after commit 4649620d9404 (thermal: core: Make thermal_zone_device_unregister() return after freeing the zone), that assignment has become redundant, because dropping the reference to the zone device does not cause the zone object to be freed any more.
 Drop it to address the NULL pointer dereference. (CVE-2023-52473)

 - In the Linux kernel, the following vulnerability has been resolved: hwrng: core - Fix page fault dead lock on mmap-ed hwrng There is a dead-lock in the hwrng device read path. This triggers when the user reads from /dev/hwrng into memory also mmap-ed from /dev/hwrng. The resulting page fault triggers a recursive read which then dead-locks. Fix this by using a stack buffer when calling copy_to_user. (CVE-2023-52615)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the CentOS 9 Stream bpftool package.
