Memory corruption during the secure boot process, when the `bootm` command is used, it bypasses the authentication of the kernel/rootfs image. Corrupción de la memoria durante el proceso de arranque seguro, cuando se utiliza el comando `bootm`, omite la autenticación de la imagen kernel/rootfs. • https://docs.qualcomm.com/product/publicresources/securitybulletin/july-2024-bulletin.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2024-6387
A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. Se encontró una condición de ejecución del controlador de señales en el servidor de OpenSSH (sshd), donde un cliente no se autentica dentro de los segundos de LoginGraceTime (120 de forma predeterminada, 600 en versiones anteriores de OpenSSH), luego se llama al controlador SIGALRM de sshd de forma asincrónica. Sin embargo, este controlador de señales llama a varias funciones que no son seguras para señales asíncronas, por ejemplo, syslog(). • https://github.com/l0n3m4n/CVE-2024-6387 https://github.com/thegenetic/CVE-2024-6387-exploit https://github.com/d0rb/CVE-2024-6387 https://github.com/devarshishimpi/CVE-2024-6387-Check https://github.com/AiGptCode/ssh_exploiter_CVE-2024-6387 https://github.com/Symbolexe/CVE-2024-6387 https://github.com/xonoxitron/regreSSHion https://github.com/PrincipalAnthony/CVE-2024-6387-Updated-x64bit https://github.com/4lxprime/regreSSHive https://github.com/shamo0/CVE-2024-6387_PoC https:&# • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-364: Signal Handler Race Condition •

In the Linux kernel, the following vulnerability has been resolved: eventfs: Fix a possible null pointer dereference in eventfs_find_events() In function eventfs_find_events,there is a potential null pointer that may be caused by calling update_events_attr which will perform some operations on the members of the ei struct when ei is NULL.

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39469 – nilfs2: fix nilfs_empty_dir() misjudgment and long loop on I/O errors
https://notcve.org/view.php?id=CVE-2024-39469
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix nilfs_empty_dir() misjudgment and long loop on I/O errors The error handling in nilfs_empty_dir() when a directory folio/page read fails is incorrect, as in the old ext2 implementation, and if the folio/page cannot be read or nilfs_check_folio() fails, it will falsely determine the directory as empty and corrupt the file system. In addition, since nilfs_empty_dir() does not immediately return on a failed folio/page read, but continues to loop, this can cause a long loop with I/O if i_size of the directory's inode is also corrupted, causing the log writer thread to wait and hang, as reported by syzbot. Fix these issues by making nilfs_empty_dir() immediately return a false value (0) if it fails to get a directory folio/page. • https://git.kernel.org/stable/c/2ba466d74ed74f073257f86e61519cb8f8f46184 https://git.kernel.org/stable/c/2ac8a2fe22bdde9eecce2a42cf5cab79333fb428 https://git.kernel.org/stable/c/405b71f1251e5ae865f53bd27c45114e6c83bee3 https://git.kernel.org/stable/c/c77ad608df6c091fe64ecb91f41ef7cb465587f1 https://git.kernel.org/stable/c/11a2edb70356a2202dcb7c9c189c8356ab4752cd https://git.kernel.org/stable/c/129dcd3e7d036218db3f59c82d82004b9539ed82 https://git.kernel.org/stable/c/d18b05eda7fa77f02114f15b02c009f28ee42346 https://git.kernel.org/stable/c/59f14875a96ef93f05b82ad3c980605f2 •
