![]() drivers/tty/vcc.c has a race condition and resultant use-after-free if a physically proximate attacker removes a VCC device while calling open(), aka a race condition between vcc_open() and vcc_remove(). ![]() ![]() In rndis_query_oid in drivers/net/wireless/rndis_wlan.c in the Linux kernel through 6.1.5, there is an integer overflow in an addition.Ītm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).Ĭbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).Īn issue was discovered in the Linux kernel through 6.2.0-rc2. When this time namespace is destroyed, the vvar page is also freed, but not removed from the process' memory, and a next page allocated by the kernel will be still available from the user-space process and can leak memory contents via this (read-only) use-after-free vulnerability. ![]() timens_install calls current_is_single_threaded to determine if the current process is single-threaded, but this call does not consider io_uring's io_worker threads, thus it is possible to insert a time namespace's vvar page to process's memory space via a page fault. NOTE: the vendor disputes the relevance of this finding because the product is not intended to protect against adversaries with this degree of local access.ĭue to a vulnerability in the io_uring subsystem, it is possible to leak kernel memory information to the user process. A threat actor can forward the existing attachment in the corresponding conversation to external groups, and the name and size of the file will not change, allowing the malware to masquerade as another file. Client mechanisms fail to validate modifications of existing cached files, resulting in an attacker's ability to insert malicious code into pre-existing attachments or replace them completely. ** DISPUTED ** Signal Desktop before 6.2.0 on Windows, Linux, and macOS allows an attacker to modify conversation attachments within the attachments.noindex directory. (Local filesystem access is needed by the attacker.) NOTE: the vendor disputes the relevance of this finding because the product is not intended to protect against adversaries with this degree of local access. In some cases, even after a self-initiated file deletion, an attacker can still recover the file if it was previously replied to in a conversation. Cached attachments are not effectively cleared. ![]() ** DISPUTED ** Signal Desktop before 6.2.0 on Windows, Linux, and macOS allows an attacker to obtain potentially sensitive attachments sent in messages from the attachments.noindex directory. The Linux kernel through 6.1.9 has a Use-After-Free in bigben_remove in drivers/hid/hid-bigbenff.c via a crafted USB device because the LED controllers remain registered for too long. Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Crafter Studio on Linux, MacOS, Windows, x86, ARM, 64 bit allows SQL Injection.This issue affects CrafterCMS v4.0 from 4.0.0 through 4.0.1, and v3.1 from 3.1.0 through 3.1.26. Afu_mmio_region_get_by_offset in drivers/fpga/dfl-afu-region.c in the Linux kernel through 6.1.12 has an integer overflow. ![]()
