https://notcve.org/view.php?id=CVE-2024-50268
In the Linux kernel, the following vulnerability has been resolved: usb: typec: fix potential out of bounds in ucsi_ccg_update_set_new_cam_cmd() The "*cmd" variable can be controlled by the user via debugfs. That means "new_cam" can be as high as 255 while the size of the uc->updated[] array is UCSI_MAX_ALTMODES (30). The call tree is: ucsi_cmd() // val comes from simple_attr_write_xsigned() -> ucsi_send_command() -> ucsi_send_command_common() -> ucsi_run_command() // calls ucsi->ops->sync_control() -> ucsi_ccg_sync_control() • https://git.kernel.org/stable/c/170a6726d0e266f2c8f306e3d61715c32f4ee41e https://git.kernel.org/stable/c/d76923164705821aa1b01b8d9d1741f20c654ab4 https://git.kernel.org/stable/c/8f47984b35f3be0cfc652c2ca358d5768ea3456b https://git.kernel.org/stable/c/604314ecd682913925980dc955caea2d036eab5f https://git.kernel.org/stable/c/69e19774f15e12dda6c6c58001d059e30895009b https://git.kernel.org/stable/c/3a2ba841659a0f15102585120dea75d8d5209616 https://git.kernel.org/stable/c/7dd08a0b4193087976db6b3ee7807de7e8316f96 •

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans During loopback communication, a dangling pointer can be created in vsk->trans, potentially leading to a Use-After-Free condition.

CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-50263 – fork: only invoke khugepaged, ksm hooks if no error
https://notcve.org/view.php?id=CVE-2024-50263
In the Linux kernel, the following vulnerability has been resolved: fork: only invoke khugepaged, ksm hooks if no error There is no reason to invoke these hooks early against an mm that is in an incomplete state. The change in commit d24062914837 ("fork: use __mt_dup() to duplicate maple tree in dup_mmap()") makes this more pertinent as we may be in a state where entries in the maple tree are not yet consistent. Their placement early in dup_mmap() only appears to have been meaningful for early error checking, and since functionally it'd require a very small allocation to fail (in practice 'too small to fail') that'd only occur in the most dire circumstances, meaning the fork would fail or be OOM'd in any case. Since both khugepaged and KSM tracking are there to provide optimisations to memory performance rather than critical functionality, it doesn't really matter all that much if, under such dire memory pressure, we fail to register an mm with these. As a result, we follow the example of commit d2081b2bf819 ("mm: khugepaged: make khugepaged_enter() void function") and make ksm_fork() a void function also. We only expose the mm to these functions once we are done with them and only if no error occurred in the fork operation. • https://git.kernel.org/stable/c/d2406291483775ecddaee929231a39c70c08fda2 https://git.kernel.org/stable/c/3b85aa0da8cd01173b9afd1f70080fbb9576c4b0 https://git.kernel.org/stable/c/985da552a98e27096444508ce5d853244019111f •
