In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix page_size variable overflow Change all variables storing mlx5_umem_mkc_find_best_pgsz() result to unsigned long to support values larger than 31 and avoid overflow. For example: If we try to register 4GB of memory that is contiguous in physical memory, the driver will optimize the page_size and try to use an mkey with 4GB entity size. The 'unsigned int' page_size variable will overflow to '0' and we'll hit the WARN_ON() in alloc_cacheable_mr().

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix a couple integer overflows on 32bit systems On 32bit systems the "off + sizeof(struct NTFS_DE)" addition can have an integer wrapping issue. Fix it by using size_add().

An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating `skb_shared_info` in the userspace, which is exploitable in systems without SMAP protection since `skb_shared_info` contains references to function pointers.

SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.

An issue in GPAC GPAC v.2.2.1 and before allows a local attacker to cause a denial of service via the Q_DecCoordOnUnitSphere function of file src/bifs/unquantize.c.

Trusty contains a vulnerability in the NVIDIA TLK kernel function where a lack of checks allows the exploitation of an integer overflow through a specific SMC call that is triggered by the user, which may lead to denial of service.

Integer overflow in the VGA module in QEMU allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) by editing VGA registers in VBE mode.

Trusty contains a vulnerability in the NVIDIA TLK kernel function where a lack of checks allows the exploitation of an integer overflow through a specific SMC call that is triggered by the user, which may lead to denial of service.

Multiple integer overflows in libwebp allows attackers to have unspecified impact via unknown vectors.

In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix signed integer overflow in l2tp_ip6_sendmsg When len >= INT_MAX - transhdrlen, ulen = len + transhdrlen will be overflow. To fix, we can follow what udpv6 does and subtract the transhdrlen from the max.

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd: fix potential integer overflow on shift of a int The left shift of int 32 bit integer constant 1 is evaluated using 32 bit arithmetic and then passed as a 64 bit function argument. In the case where i is 32 or more this can lead to an overflow. Avoid this by shifting using the BIT_ULL macro instead.

MariaDB before 10.6.5 has a sql_lex.cc integer overflow, leading to an application crash.

In the Linux kernel, the following vulnerability has been resolved: ima: Fix a potential integer overflow in ima_appraise_measurement When the ima-modsig is enabled, the rc passed to evm_verifyxattr() may be negative, which may cause the integer overflow problem.

In the Linux kernel, the following vulnerability has been resolved: i2c: designware: use casting of u64 in clock multiplication to avoid overflow In functions i2c_dw_scl_lcnt() and i2c_dw_scl_hcnt() may have overflow by depending on the values of the given parameters including the ic_clk. For example in our use case where ic_clk is larger than one million, multiplication of ic_clk * 4700 will result in 32 bit overflow. Add cast of u64 to the calculation to avoid multiplication overflow, and use the corresponding define for divide.

In the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: Fix potential integer multiplication overflow errors When multiplying of different types, an overflow is possible even when storing the result in a larger type. This is because the conversion is done after the multiplication. So arithmetic overflow and thus in incorrect value is possible. Correct an instance of this in the inter packet delay calculation. Fix by ensuring one of the operands is u64 which will promote the other to u64 as well ensuring no overflow.

In the Linux kernel, the following vulnerability has been resolved: af_netlink: Fix shift out of bounds in group mask calculation When a netlink message is received, netlink_recvmsg() fills in the address of the sender. One of the fields is the 32-bit bitfield nl_groups, which carries the multicast group on which the message was received. The least significant bit corresponds to group 1, and therefore the highest group that the field can represent is 32. Above that, the UB sanitizer flags the out-of-bounds shift attempts. Which bits end up being set in such case is implementation defined, but it's either going to be a wrong non-zero value, or zero, which is at least not misleading. Make the latter choice deterministic by always setting to 0 for higher-numbered multicast groups. To get information about membership in groups >= 32, userspace is expected to use nl_pktinfo control messages[0], which are enabled by NETLINK_PKTINFO socket option. [0] https://lwn.net/Articles/147608/ The way to trigger this issue is e.g. through monitoring the BRVLAN group: # bridge monitor vlan & # ip link add name br type bridge Which produces the following citation: UBSAN: shift-out-of-bounds in net/netlink/af_netlink.c:162:19 shift exponent 32 is too large for 32-bit type 'int'

In the Linux kernel, the following vulnerability has been resolved: drm/bridge: anx7625: Fix overflow issue on reading EDID The length of EDID block can be longer than 256 bytes, so we should use `int` instead of `u8` for the `edid_pos` variable.

In wlan driver, there is a possible missing params check. This could lead to local denial of service in wlan services.
