firefox: thunderbird: Memory safety bugs fixed in Firefox 138, Thunderbird 138, Firefox ESR 128.10, and Thunderbird 128.10

A flaw was found in Firefox. The Mozilla Foundation's Security Advisory describes the following issue: Memory safety bugs present in Firefox 137, Thunderbird 137, Firefox ESR 128.9, and Thunderbird 128.9. Some of these bugs showed evidence of memory corruption, and we presume that with enough...

firefox: thunderbird: Memory safety bug fixed in Firefox ESR 128.10 and Thunderbird 128.10

A flaw was found in Firefox. The Mozilla Foundation's Security Advisory describes the following issue: Memory safety bug present in Firefox ESR 128.9, and Thunderbird 128.9. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run...

rust-openssl: rust openssl ssl::select_next_proto use after free

A flaw was found in the rust-openssl package. In certain versions, ssl::selectnextproto can return a slice pointing into the server argument's buffer but with a lifetime bound to the client argument. In situations where the sever buffer's lifetime is shorter than the client buffer's, this can cau...

kernel: Bluetooth: hci_core: Fix not checking skb length on hci_acldata_packet

A use-after-free vulnerability was found in the Linux kernel. The Bluetooth firmware isn't checked if skb contains an ACL header, otherwise the code may attempt to access some uninitialized or invalid memory past the valid skb-data...

kernel: spi: nxp-fspi: fix the KASAN report out-of-bounds bug

A flaw was found in the Linux kernel. An out-of-bounds write vulnerability exists in the nxp-fspi driver when handling data that is not 4-byte aligned during write operations to the TX FIFO. A local attacker with administrative privileges could exploit this flaw, potentially leading to a system...

kernel: dm cache: fix potential out-of-bounds access on the first resume

In the Linux kernel, the following vulnerability has been resolved: dm cache: fix potential out-of-bounds access on the first resume Out-of-bounds access occurs if the fast device is expanded unexpectedly before the first-time resume of the cache table. This happens because expanding the fast...

kernel: usb: dwc3: core: Prevent USB core invalid event buffer address access

A flaw was found in the Linux kernel's USB dwc3 core. During runtime suspend, the USB core could attempt to access an invalid event buffer address. This issue, particularly affecting Exynos platforms, can lead to System Memory Management Unit SMMU faults and other memory-related problems,...

kernel: idpf: fix UAFs when destroying the queues

In the Linux kernel, the following vulnerability has been resolved: idpf: fix UAFs when destroying the queues The second tagged commit started sometimes very rarely, but possible throwing WARNs from net/core/pagepool.c:pagepooldisabledirectrecycling. Turned out idpf frees interrupt vectors with...

kernel: smb: client: fix possible double free in smb2_set_ea()

A doubly freeing memory vulnerability exists in the Linux kernel smb client. After the first successful memory allocation for 'ea', the second memory release for 'ea' will result in double free, leading to loss of availability of the system...

kernel: bpf: add missing check_func_arg_reg_off() to prevent out-of-bounds memory accesses

bpf in linux kernel permits passing in a modified CONSTPTRTODYNPTR to a global function as an argument. BPF helpers can use the modified CONSTPTRTODYNPTR within a global function context, which can lead to out of bounds memory accesses...

kernel: Bluetooth: qca: add missing firmware sanity checks

A flaw was found in the Linux kernel's Bluetooth QCA driver. This vulnerability is caused by missing sanity checks when parsing firmware files before downloading them. A local attacker with low privileges could exploit this to corrupt memory beyond a vmalloced buffer, potentially leading to a...

kernel: sctp: properly validate chunk size in sctp_sf_ootb()

In the Linux kernel, the following vulnerability has been resolved: sctp: properly validate chunk size in sctpsfootb A size validation fix similar to that in Commit 50619dbf8db7 "sctp: add size validation when walking chunks" is also required in sctpsfootb to address a crash reported by syzbot:...

kernel: slip: make slhc_remember() more robust against malicious packets

A flaw was found in the Linux kernel. The slhcremember function, which handles Serial Line Internet Protocol SLIP header compression, did not properly validate incoming packet sizes and headers. A local attacker could exploit this by sending specially crafted malicious packets, leading to an...

kernel: ACPI: sysfs: validate return type of _STR method

A flaw was found in the Linux kernel. This vulnerability occurs in the ACPI Advanced Configuration and Power Interface system file system sysfs when processing the STR method. If a non-buffer object is returned, the system attempts to access invalid memory. A local attacker could exploit this to...

kernel: drm/dp_mst: Ensure mst_primary pointer is valid in drm_dp_mst_handle_up_req()

In the Linux kernel, the following vulnerability has been resolved: drm/dpmst: Ensure mstprimary pointer is valid in drmdpmsthandleupreq While receiving an MST up request message from one thread in drmdpmsthandleupreq, the MST topology could be removed from another thread via...

xorg: xwayland: Out-of-bounds write in CreatePointerBarrierClient()

An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching...

X.Org: Xwayland: Use-after-free of the root cursor

A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server as a global variable. If a client frees the root cursor, the internal reference points to freed memory and causes a use-after-free...
