CVE-2019-19807 – kernel: use-after-free in sound/core/timer.c
https://notcve.org/view.php?id=CVE-2019-19807
15 Dec 2019 — In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code refactoring, aka CID-e7af6307a8a5. This is related to snd_timer_open and snd_timer_close_locked. The timeri variable was originally intended to be for a newly created timer instance, but was used for a different purpose after refactoring. En el kernel de Linux versiones anteriores a la versión 5.3.11, el archivo sound/core/timer.c tiene un uso de la memoria previamente liberada causado por una refactorización... • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.11 • CWE-416: Use After Free •
CVE-2019-19767 – kernel: use-after-free in __ext4_expand_extra_isize and ext4_xattr_set_entry related to fs/ext4/inode.c and fs/ext4/super.c
https://notcve.org/view.php?id=CVE-2019-19767
12 Dec 2019 — The Linux kernel before 5.4.2 mishandles ext4_expand_extra_isize, as demonstrated by use-after-free errors in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c, aka CID-4ea99936a163. El kernel de Linux versión anterior a 5.4.2 maneja inapropiadamente la función ext4_expand_extra_isize, como es demostrado por un error de uso de la memoria previamente liberada en las funciones __ext4_expand_extra_isize y ext4_xattr_set_entry, relacionadas con los archivos fs/ex... • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html • CWE-416: Use After Free •

CVE-2019-19770 – kernel: use-after-free in debugfs_remove in fs/debugfs/inode.c
https://notcve.org/view.php?id=CVE-2019-19770
12 Dec 2019 — In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously created with a call to another debugfs function such as debugfs_create_file). NOTE: Linux kernel developers dispute this issue as not being an issue with debugfs, instead this is an issue with misuse of debugfs within blktrace ** EN DISPUTA ** En el kernel de Linux versión 4.19.83, presenta un uso de la memoria previame... • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00035.html • CWE-416: Use After Free •
