Race condition in the firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

kernel: the get_user_pages implementation when used for a copy-on-write page does not properly consider the semantics of read operations and therefore can grant unintended read access

An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/huge_memory.c. The get_user_pages (aka gup) implementation, when used for a copy-on-write page, does not properly consider the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58.

hw: observable timing discrepancy in some Intel Processors

Observable timing discrepancy in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

hw: improper isolation of shared resources in some Intel Processors

Improper isolation of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

kernel: DoS via concurrent calls to dw_spi_irq and dw_spi_transfer_one functions in drivers/spi/spi-dw.c

An issue was discovered in the Linux kernel before 5.4.17. drivers/spi/spi-dw.c allows attackers to cause a panic via concurrent calls to dw_spi_irq and dw_spi_transfer_one, aka CID-19b61392c5a8.

Out of bounds write in the firmware for some Intel(R) Processors may allow a privileged user to potentially enable denial of service via local access.

Improper initialization in the firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

kernel: memory leak in mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c

mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c in the Linux kernel before 5.1.6 has some error-handling cases that did not free allocated hostcmd memory, aka CID-003b686ace82. This will cause a memory leak and denial of service.

kernel: NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery

In the Linux kernel through 5.4.6, there is a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition, aka CID-f70267f379b5.

kernel: NULL pointer dereference in relay_open in kernel/relay.c

relay_open in kernel/relay.c in the Linux kernel through 5.4.1 allows local users to cause a denial of service (such as relay blockage) by triggering a NULL alloc_percpu result.

kernel: A memory leak in the cx23888_ir_probe() function in drivers/media/pci/cx23885/cx23888-ir.c allows attackers to cause a DoS

A memory leak in the cx23888_ir_probe() function in drivers/media/pci/cx23885/cx23888-ir.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering kfifo_alloc() failures, aka CID-a7b2df76b42b.

Out of bounds read in the firmware for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege via local access.

Insufficient control flow management in the firmware for some Intel(R) Processors may allow an unauthenticated user to potentially enable escalation of privilege via physical access.

Kernel: use after free bug in btsdio_remove due to race condition

A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. A call to btsdio_remove with an unfinished job may cause a race problem which leads to a UAF on hdev devices.

Vim < v9.1.0648 has a double-free in dialog_changed()

Vim is an open source command line text editor. double-free in dialog_changed() in Vim < v9.1.0648. When abandoning a buffer, Vim may ask the user what to do with the modified buffer. If the user wants the changed buffer to be saved, Vim may create a new Untitled file, if the buffer did not have a name yet. However, when setting the buffer name to Unnamed, Vim will falsely free a pointer twice, leading to a double-free and possibly later to a heap-use-after-free, which can lead to a crash. The issue has been fixed as of Vim patch v9.1.0648.

Vim has heap-use-after-free at /src/charset.c:1770:12 in skipwhite

Vim is a UNIX editor that, prior to version 9.0.2121, has a heap-use-after-free vulnerability. When executing a `:s` command for the very first time and using a sub-replace-special atom inside the substitution part, it is possible that the recursive `:s` call causes free-ing of memory which may later then be accessed by the initial `:s` command. The user must intentionally execute the payload and the whole process is a bit tricky to do since it seems to work only reliably for the very first :s command. It may also cause a crash of Vim. Version 9.0.2121 contains a fix for this issue.

intel-microcode: Improper input validation in some Intel® TDX module software

Improper input validation in some Intel(R) TDX module software before version 1.5.05.46.698 may allow a privileged user to potentially enable escalation of privilege via local access.

intel-microcode: Improper input validation in some Intel(R) TDX module software

Improper input validation in some Intel(R) TDX module software before version 1.5.05.46.698 may allow a privileged user to potentially enable escalation of privilege via local access.

Use-after-free in Linux kernel's netfilter: nf_tables component

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.
