paxtest handles temporary files insecurely
xtrlock through 2.10 does not block multitouch events. Consequently, an attacker at a locked screen can send input to (and thus control) various programs such as Chromium via events such as pan scrolling, "pinch and zoom" gestures, or even regular mouse clicks (by depressing the touchpad once and then clicking with a different finger).
A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. When a local user in the guest writes an executable file with SUID or SGID, none of these privileged bits are correctly dropped. As a result, in rare circumstances, this flaw could be used by malicious users in the guest to elevate their privileges within the guest and help a host local user to elevate privileges on the host.
IBM Spectrum Scale 5.1.0 through 5.1.1.1 could allow a privileged admin to destroy filesystem audit logging records before expiration time. IBM X-Force ID: 209164.
drivers/net/ethernet/xilinx/xilinx_emaclite.c in the Linux kernel before 5.13.3 makes it easier for attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM pointer).
The DBI library (libdbi-perl) for Perl allows local users to overwrite arbitrary files via a symlink attack on a temporary PID file.
driver/subprocs.c in XScreenSaver before 5.34 does not properly perform an internal consistency check, which allows physically proximate attackers to bypass the lock screen by hot swapping monitors.

The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c.
It was discovered that the get_modified_conffiles() function in backends/packaging-apt-dpkg.py allowed injecting modified package names in a manner that would confuse the dpkg(1) call.
Nextcloud Server is a Nextcloud package that handles data storage. In versions priot to 19.0.13, 20.0.11, and 21.0.3, Nextcloud Server audit logging functionality wasn't properly logging events for the unsetting of a share expiration date. This event is supposed to be logged. This issue is patched in versions 19.0.13, 20.0.11, and 21.0.3.
